Digital signature

You can make digital signatures with your phone if your SIM card has a security

module. Using the digital signature can be the same as signing your name to a

paper bill, contract, or other document.

To make a digital signature, select a link on a page, such as the title of the book

you want to buy and its price. The text to sign is displayed, which may include the

amount and date.

Check that the header text is Read and that the digital signature icon is shown.

If the digital signature icon does not appear, there is a security breach, and you

should not enter any personal data such as your signing PIN.

To sign the text, read all of the text first, and select Sign.

The text may not fit within a single screen. Therefore, make sure to scroll through

and read all of the text before signing.

Select the user certificate you want to use. Enter the signing PIN (see ”Access

codes,” p. 8), and select OK. The digital signature icon disappears, and the service

may display a confirmation of your purchase.
